I've just started the Expedition and am fighting the initial invasion with Aegis. My SMG burst attacks now seem to randomly fire no shots instead of 5 or 7. The initial "shooting stance" animation plays, the target is suppressed, and my action points (or Gun Rush) are used up. However, once the start-up is finished the player character just stands in idle pose instead of firing.
Here are 2 short videos showing the issue. The first video is with Gun Rush active, the second is without (sorry if they appear dim):

I'm using two SMGs, both with Rapid Reloaders and one (the Impala) with a Muzzle Brake. My character's burst-related feats are Spec Ops, Suppressive Fire, Opportunist, and Commando (with no spec points put into it).
